Bottom partner B' and Zb production at the LHC

Abstract

Some new physics models, such as "beautiful mirrors" scenario, predict the existence of the bottom partner $B^{\prime }$. Considering the constraints from the data for the $Z\to b\bar{b}$ branching ratio $R_b$ and the $FB$ asymmetry $A_{FB}^b$ on the relevant free parameters, we calculate the contributions of $B^{\prime }$ to the cross section $\sigma (Zb)$ and the $Z$ polarization asymmetry $A_Z$ for $Zb$ production at the $LHC$. We find that the bottom partner $B^{\prime }$ can generate significant corrections to $\sigma (Zb)$ and $A_Z$, which might be detected in near future.
